Describe Data structures used during passes of assembler and their use.

During passes of assembler, the Data structures define as:

Pass 1 data base

  • Input source program
  • A location counters (LC)
  • A machine-operation table (i.e. MOT), which indicates the symbolic mnemonic for each instruction and instruction's length.
  • Pseudo- operation table
  • Symbol table
  • Literal table
  • Copy of the input to be used later through pass 2

Pass 2

  • Coping of source program input to pass 1
  • Location counter (LC)
  • MOT
  • POT
  • ST
  • Base table which indicates that registers are currently identified as base register.
  • A work space, INST, which used to hold instruction as its different parts are being assembled together
  • Punch line, utilized to produce a printed listing.
  • Punch card used for converting assembled instructions in the format required by the loader.
